| shikamaru317 said: 3x PS4 isn't exactly equivalent to Titan X, because PS4 uses an AMD graphics chipset. AMD gflops do not equal Nividia gflops for whatever reason. For instance the 5600 gflops AMD R9 290x is siginifcantly weaker than the 6100 gflops Titan X, it's closer to the 4600 gflops GTX 980. Assuming that Sony and Microsoft go with AMD APU solutions again next-gen to cut costs, and assuming a 5-6 year generation, I believe that PS5 and Xbox 4 will fall somewhere between 5000 and 6000 gflops when they release in 2018-2019, so roughly equivalent to an R9 290x. Graphics like this recent Witcher 3 launch cinematic will simply be impossible on consoles next-gen imo, even at 1080p, let alone 1440p or 4k. However, PS5 and Xbox 4 might just be able to achieve the visuals of 2010-2011 CGI trailers in real-time, for instance the visual of the SWTOR cinematics. |
A 2019 release will probably mean 10nm on both TSMC and GlobalFoundries. That's a 8x improvement over the 28nm AMD's currently stuck on. Of course, power consumption might not improve that much, specially since it's AMD we're talking about, or we might be sticking with 14nm Finfets for as long as we were on 28nm. Still, R9 290X levels seem too low since Nvidia manages about the same performance with their 145W GTX 970 - somewhat close already to the 110W TDP of the Radeon HD 7850 in the PS4. Personally I'd envision a 6x power consumption improvement for AMD, and roughly a 11.4 TFLOPS GPU for a PS4 equivalent by 2019.
